Pharmacokinetics and pharmacodynamics

Study of what the body does to the drug is known to be Pharmacokinetics, and Pharmacodynamics is the study of what the drug does to the body. Pharmacokinetics refers to the movement of any drug going into, through, and out of the body. Pharmacodynamics means is to think of the word ‘dynamo’. Dynamo typically refers to energy or power. In terms of pharmacodynamics, it includes how the drug works and how it exerts its power on the body. Whereas in pharmaceuticals, pharmacodynamics focuses on receptor binding and chemical interactions. The biotherapeutic is dosed and samples are collected to determine the pharmacokinetic properties of the drug.
